All information you need is provided in <observed_from_primary_session> messages. Create observations from what you observe - no investigation needed.\n\nYour job is to monitor a different Claude Code session happening RIGHT NOW, with the goal of creating observations and progress summaries as the work is being done LIVE by the user. You are NOT the one doing the work - you are ONLY observing and recording what is being built, fixed, deployed, or configured in the other session.\n\nSPATIAL AWARENESS: Tool executions include the working directory (tool_cwd) to help you understand:\n- Which repository/project is being worked on\n- Where files are located relative to the project root\n- How to match requested paths to actual execution paths\n\nWHAT TO RECORD\n--------------\nFocus on durable technical signal:\n- What the system NOW DOES differently (new capabilities)\n- What shipped to users/production (features, fixes, configs, docs)\n- Changes in technical domains (auth, data, UI, infra, DevOps, docs)\n- Concrete debugging or investigative findings from logs, traces, queue state, database rows, and code-path inspection\n\nUse verbs like: implemented, fixed, deployed, configured, migrated, optimized, added, refactored, discovered, confirmed, traced\n\n✅ GOOD EXAMPLES (describes what was built or learned):\n- \"Authentication now supports OAuth2 with PKCE flow\"\n- \"Deployment pipeline runs canary releases with auto-rollback\"\n- \"Database indexes optimized for common query patterns\"\n- \"Observation queue for claude-mem session timed out waiting for an agent pool slot\"\n- \"Fallback processing abandoned pending messages after Gemini and OpenRouter returned 404\"\n\n❌ BAD EXAMPLES (describes observation process - DO NOT DO THIS):\n- \"Analyzed authentication implementation and stored findings\"\n- \"Tracked deployment steps and logged outcomes\"\n- \"Monitored database performance and recorded metrics\"\n\nWHEN TO SKIP\n------------\nSkip routine operations:\n- Empty status checks\n- Package installations with no errors\n- Simple file listings with no follow-on finding\n- Repetitive operations you've already documented\n- File related research that comes back empty or not found\n\nIf skipping, return an empty response only. Do not explain the skip in prose.\n\nIMPORTANT: Continue generating observations from tool use messages using the XML structure below.\n\nOUTPUT FORMAT\n-------------\nOutput observations using this XML structure:\n\n<observation>\n  <type>[ bugfix | feature | refactor | change | discovery | decision | security_alert | security_note ]</type>\n  \n  <title>[title: Short title capturing the core action or topic]</title>\n  <subtitle>[subtitle: One sentence explanation (max 24 words)]</subtitle>\n  <facts>\n    <fact>[Concise, self-contained statement]</fact>\n    <fact>[Concise, self-contained statement]</fact>\n    <fact>[Concise, self-contained statement]</fact>\n  </facts>\n  <!--\n    facts: Concise, self-contained statements\nEach fact is ONE piece of information\n      No pronouns - each fact must stand alone\n      Include specific details: filenames, functions, values\n\nfiles\n…(truncated, 1828 more chars)\n\nTurn 1 — Assistant\n\n(No observations to record from this message)\n\nTurn 2 — User\n\n--- MODE SWITCH: PROGRESS SUMMARY ---\n⚠️ CRITICAL TAG REQUIREMENT — READ CAREFULLY:\n• You MUST wrap your ENTIRE response in <summary>...</summary> tags.\n• Do NOT use <observation> tags. <observation> output will be DISCARDED and cause a system error.\n• The ONLY accepted root tag is <summary>. Any other root tag is a protocol violation.\n\nPROGRESS SUMMARY CHECKPOINT\n===========================\nWrite progress notes of what was done, what was learned, and what's next. This is a checkpoint to capture progress so far. The session is ongoing - you may receive more requests and tool executions after this summary. Write \"next_steps\" as the current trajectory of work (what's actively being worked on or coming up next), not as post-session future work. Always write at least a minimal summary explaining current progress, even if work is still in early stages, so that users see a summary output tied to each request.\n\nClaude's Full Response to User:\nGood. So buildSuccessFields receives NhrDocumentContentResult[] — the base tpf type with no status on items. To stay generic, the wrapper can't cast to ContentResult[].\n\nSecond question:\n\nThe wrapper's two code paths are:\n- buildSuccessFields — called when no exception was thrown\n- catch block — called when the adapter throws\n\nIf DmpNhrAdapter always returns an array (never throws for result-level errors), the catch path never fires for per-item errors, so the wrapper has no signal to emit status/error_code/error_message. That means DmpNhrAdapter must throw to communicate error/partial-success state — but then the array of partial results is lost to useGetDocumentsContent.\n\nShould DmpNhrAdapter.getDocumentsContent throw a custom error that carries both the aggregate status/code/message AND the partial results array, so the hook can catch it and still render what it has?\n\nMy recommendation: yes — define a local NhrContentOperationError extends Error with { results: ContentResult[], status: NhrResultStatus, code?: string }. The wrapper's catch block reads status and code via duck-typing (no import needed). The hook catches it and calls setDocumentsContent(e.results) for partial results.\n\nRespond in this XML format:\n<summary>\n  <request>[Short title capturing the user's request AND the substance of what was discussed/done]</request>\n  <investigated>[What has been explored so far?

DO NOT do any work right now other than generating this next PROGRESS SUMMARY - and remember that you are a memory agent designed to summarize a DIFFERENT claude code session, not this one.\n\nNever reference yourself or your own actions. Do not output anything other than the summary content formatted in the XML structure above. All other output is ignored by the system, and the system has been designed to be smart about token usage. Please spend your tokens wisely on useful summary content.\n\nThank you, this summary will be very useful for keeping track of our progress!\n\nTurn 2 — Assistant\n\n<summary>\n  <request>Design error handling strategy for DmpNhrAdapter.getDocumentsContent — how to communicate partial results and error state through a generic wrapper</request>\n  <investigated>The wrapper's two code paths (success via buildSuccessFields, catch block for exceptions) and the adapter's return behavior (always returns array vs throws for errors). Examined the problem that per-item errors aren't signaled if the adapter never throws, leaving the wrapper unable to emit status/error_code/error_message while keeping the wrapper generic and avoiding casts.</investigated>\n  <learned>If DmpNhrAdapter always returns an array without throwing on per-item failures, the catch block in the wrapper never fires for those errors, so the wrapper has no signal to emit error metadata. The wrapper cannot cast results to ContentResult[] to stay generic. A custom error type can carry both aggregate error metadata (status, code) and the partial results array, bridging the gap between loss of results on exception and the need to communicate error state.</learned>\n  <completed>Architectural analysis of error handling constraints and flow through the adapter-wrapper-hook chain. Identified the core tension: throwing loses partial results, not throwing leaves no signal for error metadata. Drafted recommendation for NhrContentOperationError pattern with structured error data.</completed>\n  <next_steps>Likely implementation of custom NhrContentOperationError class that extends Error with { results: ContentResult[], status: NhrResultStatus, code?: string }. Update DmpNhrAdapter to throw this error type on failures. Modify wrapper's catch block to read status/code via duck-typing (no imports). Update hook to catch the error and call setDocumentsContent(e.results) for partial-result rendering.</next_steps>\n  <notes>This pattern uses duck-typing to avoid tight coupling — the wrapper doesn't import adapter types but still reads error fields at runtime. Keeps the wrapper generic while enabling rich error context. Preserves partial results through the exception path, critical for user-facing partial-success states.</notes>\n</summary>\n\nTurn 3 — User\n\n--- MODE SWITCH: PROGRESS SUMMARY ---\n⚠️ CRITICAL TAG REQUIREMENT — READ CAREFULLY:\n• You MUST wrap your ENTIRE response in <summary>...</summary> tags.\n• Do NOT use <observation> tags. <observation> output will be DISCARDED and cause a system error.\n• The ONLY accepted root tag is <summary>.

This is a checkpoint to capture progress so far. The session is ongoing - you may receive more requests and tool executions after this summary. Write \"next_steps\" as the current trajectory of work (what's actively being worked on or coming up next), not as post-session future work. Always write at least a minimal summary explaining current progress, even if work is still in early stages, so that users see a summary output tied to each request.\n\nClaude's Full Response to User:\nGood. Next question to resolve before implementation:\n\nThird question:\n\nNhrContentOperationError carries results: ContentResult[]. Both DmpNhrAdapter (which throws it) and useGetDocumentsContent (which catches and reads .results) need to import it — so it can't live in DmpNhrAdapter.ts.\n\nWhere should it be defined?\n\nOptions:\n- src/business/types.ts — alongside ContentResult, already the shared type layer\n- src/business/errors.ts — new file, keeps error classes separate from data types  \n- src/business/adapters/nhrErrors.ts — adapter-layer scoped, but the hook would depend on the adapter layer (wrong direction)\n\nMy recommendation: src/business/errors.ts — error classes are distinct from data shape types, and both DmpNhrAdapter and useGetDocumentsContent can import from src/business/ without layer-crossing.\n\nRespond in this XML format:\n<summary>\n  <request>[Short title capturing the user's request AND the substance of what was discussed/done]</request>\n  <investigated>[What has been explored so far?

Please spend your tokens wisely on useful summary content.\n\nThank you, this summary will be very useful for keeping track of our progress!\n\nTurn 3 — Assistant\n\n<summary>\n  <request>Determine appropriate file location for NhrContentOperationError custom error class — resolving import dependencies between adapter and hook</request>\n  <investigated>Three candidate locations for the error class: src/business/types.ts (shared type layer), src/business/errors.ts (dedicated error file), and src/business/adapters/nhrErrors.ts (adapter-scoped). Examined import constraints — both DmpNhrAdapter and useGetDocumentsContent must import the error class, so it cannot live in adapter-layer-only scope.</investigated>\n  <learned>Error classes and data shape types are distinct concerns that should live in separate files. Both the adapter (which throws) and hook (which catches) can safely import from src/business/ level without violating layer boundaries. Adapter-layer scoping creates wrong dependency direction (hook depending on adapter layer).</learned>\n  <completed>Architectural decision on error class placement. Evaluated three options and identified constraints that rule out adapter-scoped definition. Selected src/business/errors.ts as the appropriate location.</completed>\n  <next_steps>Create src/business/errors.ts with NhrContentOperationError class definition including results: ContentResult[], status: NhrResultStatus, and optional code properties. Update DmpNhrAdapter to import and throw NhrContentOperationError. Update useGetDocumentsContent hook to import and catch the error, reading partial results from the exception.</next_steps>\n  <notes>This maintains clean separation of concerns — types in types.ts, errors in errors.ts — while enabling bidirectional imports within the src/business/ layer. Avoids layer-crossing that would occur if hook imported from adapter-scoped error definitions.</notes>\n</summary>\n\nTurn 4 — User\n\n--- MODE SWITCH: PROGRESS SUMMARY ---\n⚠️ CRITICAL TAG REQUIREMENT — READ CAREFULLY:\n• You MUST wrap your ENTIRE response in <summary>...</summary> tags.\n• Do NOT use <observation> tags. <observation> output will be DISCARDED and cause a system error.\n• The ONLY accepted root tag is <summary>.

Write \"next_steps\" as the current trajectory of work (what's actively being worked on or coming up next), not as post-session future work. Always write at least a minimal summary explaining current progress, even if work is still in early stages, so that users see a summary output tied to each request.\n\nClaude's Full Response to User:\nGood. One more design decision before implementing:\n\nFourth question:\n\nDmpNhrAdapter aggregates the ContentResult[]. The aggregate status can be 'success', 'partial success', or 'error'. The wrapper only captures status/code/message via the catch path — meaning only when the adapter throws.\n\nUnder which conditions should the adapter throw NhrContentOperationError?\n\n- Only on full error (all results have status: 'error'): partial success items are returned normally, monitoring only captures full failures\n- Any non-full-success (at least one 'error' or 'partial success' item): throw carries all results + aggregate status, hook always uses e.results\n\nMy recommendation: any non-full-success — throw whenever there is at least one error or partial-success item. This gives monitoring visibility into partial success (categorization missing, CDA parse issues) in addition to full failures, and the hook uses e.results uniformly for all non-success cases.\n\nRespond in this XML format:\n<summary>\n  <request>[Short title capturing the user's request AND the substance of what was discussed/done]</request>\n  <investigated>[What has been explored so far?

Throwing on any non-full-success gives broader observability of degradation, treats partial and full failures similarly, and allows the hook to use a single code path (e.results) for all non-success outcomes rather than branching on success vs exception.</learned>\n  <completed>Design decision: adapter should throw NhrContentOperationError for any non-full-success condition (not just full errors). Rationale includes monitoring visibility and uniform hook handling.</completed>\n  <next_steps>Implement DmpNhrAdapter.getDocumentsContent to aggregate status from ContentResult[] items, throw NhrContentOperationError when aggregate status is not 'success', and pass all results + aggregate status/code in the thrown error. Implement useGetDocumentsContent hook to catch the error and call setDocumentsContent(e.results) for partial-result rendering with error metadata available for UI display.</next_steps>\n  <notes>This decision prioritizes observability and code simplicity in the hook — partial-success cases now surface monitoring alerts and are handled by the same error path as full failures. The wrapper's catch block becomes the primary handler for all degraded states, not just catastrophic failures.</notes>\n</summary>",
